Personally, I think registering this charset will be counter-productive to
the acceptance of Unicode and is a bad idea.

The more variant encodings of Unicode that end up used in practice, the
more people will hate Unicode and want to use their good old localized
character set which "just worked." While Unicode is a relatively easy
sell to implementors it is a hard sell to end-users and more encoding
schemes just makes it that much harder.

This encoding scheme is particularly bad because it can't be used in a
MIME text/* media type and it permits NUL octets, so it will have to be
encoded in most transport environments.
